puzzles: refactor and resync with upstream

This brings puzzles up-to-date with upstream revision
2d333750272c3967cfd5cd3677572cddeaad5932, though certain changes made
by me, including cursor-only Untangle and some compilation fixes
remain. Upstream code has been moved to its separate subdirectory and
future syncs can be done by simply copying over the new sources.

-Range
-<p>
-Colour some squares black, so as to meet the following conditions:
-<ul>
-<li>
-No two black squares are orthogonally adjacent.
-<li>
-No group of white squares is separated from the rest of the grid by
-black squares.
-<li>
-Each numbered cell can see precisely that many white squares in
-total by looking in all four orthogonal directions, counting itself.
-(Black squares block the view. So, for example, a 2 clue must be
-adjacent to three black squares or grid edges, and in the fourth
-direction there must be one white square and then a black one beyond
-it.)
-</ul>

-Left-click to colour a square black. Right-click to mark a square
-with a dot, if you know it should not be black.
